Jim Beam is the world’s best-selling bourbon brand. The drink meets all the requirements for real bourbon: produced in Kentucky, the raw material is mainly corn (51%), aged for at least four years in American oak barrels charred inside, which gives a noticeable caramel flavor. The quality of the spring water used, which undergoes natural filtration, also plays a huge role since the distillery is located on a limestone layer. Other secret ingredients of the brand’s success are a traditional grain blend recipe, a particular yeast strain, and absolute dedication.
